Problema Solution
One angle is 21 less than 2 times another. Find the measure of each angle if:
a. They are complements of each other.
b. They are supplements of each other.

let 'x' represent one angle, then '2x-21' represents the other
if they are complements of each other:
x + 2x-21 = 90
solving for 'x' we have x=37
90 - 37 = 53
the angles are 37 and 53
if they are supplements of each other:
x + 2x-21 = 180
solving for 'x' we have x=67
180 - 67 = 113
the angles are 67 and 113
